Vocal Cord Actinomycosis Mimicking a Laryngeal Tumor

摘要

Laryngeal carcinoma and laryngeal papilloma are the most commonly encountered tumorous lesions in the larynx. Herein, we report a case of the mass arising from the left vocal cord in a 49-year-old Japanese man. Endoscopic examination suggested that the mass is a tumor such as carcinoma and papilloma. Pathological examination showed that the specimen demonstrated actinomycosis in the left vocal cord. Although vocal cord actinomycosis is extremely rare, the otolaryngologist should recognize this condition during the inspection of the larynx.
